Copyright notes: All works by Juan Gris done 1906 or later were first published in France, and as such their copyright had expired by the URAA date, even including war extensions. Therefore they are in the public domain in both the US and their source country. His works before 1906 are in the public domain in the US due to predating 1923, and in the public domain in Spain because he has been dead for at least 80 years.
